BEER-y-TAP.

SPECIFICATION forming part of Letters Patent-No. 277,872, dated May 22, 1883. v

Application tiled January 2, 1883.

To all whom it may concern.-

Be itknown that we, WILLIAM O. BOONE and WILLIAM A. WHITFIELD, both of Brooklyn,

` in the county of Kings and. State of New York,

have invented certain Improvements in Beer- Taps, of which the following is a specification.

In beer-taps as ordinarily constructed the valve which controls the exit of the liquid works within a' narrow tube or sleeve, which ternally with a xed nut, a.

a'ords but a slight annular space for the passage ot' the liquid, so that in case the valve swells-a very common occurrence-the passageis obstructed and the device4 rendered nearly or quite useless for the purposes for which it is designed. Furthermore, such beertaps are comparatively complicated,expensive, and liable to get out ot' order.

The object of our invention is to provide an apparatus of the class specified which will be free from the drawbacks referred to, and which can he manufactured and applied to use at a moderate cost and with the exercise of merely ordinary mechanical skill. f

The invention comprises certain novel coinbinations oi parts whereby said objects are effectual! y secured.

Figure l is a central longitudinal sectional view ot' an apparatus constructed according to our invention and applied to use on a Cask or barrel. Fig. 2 is an end view, as seen from the right of Fig. 1, oi' certain parts of said apparatus. Fig. 3 is a side view and partial section oi a portion of said apparatus, including a modiiication thereof. Fig. 4 isa transverse sectional View taken in the line :um of Fig.3. Fig. 5 is a transverse sectional View taken in vthe line y y ot' Fig. l. Fig.l Gis a sectional view, seen `from the right-hand side, showing a modification in said apparatus.

A is the bushing, composed vof the inner tapering externally-threaded part, A', and the vouter circular or cylindrical enlarged portion,

B'. The part A is screwed into a suitablyshaped socket'formed in the side of the barrel or cask IC, while the part B lits into a circular rabbet at the outer portion of the socket aforesaid, all as'will he understood by reference to Fig. 1. The bushing Ais provided in- Its outer portion, B', is also provided with an internal screwthread, b. Upon the shoulder a 0f the nut a is placed an annular Washer or packing-rin g, C',

(No model.) e

[and upon this rests the circumferentiallylianged inner end of a tapering shell, I), the inner portion ot' which is cylindrical, as shown at c. Anv externally-threaded sleeve or annu- .lar nut, E, is screwed into the internal screw,

, thread,f1,at its inner end,which works through a fixed nut, m, secured upon or formed in a cross-piece, a, provided internally to the shell D, the outer extremity ot' the latter being externally threaded to receive a gland, i', which compresses the packing-ring around the valve- 'actnating stem h, to prevent leakage from y the end ofv the shell D. Screwed into the nut c of the bushing'is a block, F, which has at its outer end a liange, s, which rests upon the inwardly-projecting edge of the packing-ring O. so that the block F is iirrnly and tightly held in place.

G' is the valve, provided upon the valve-stem H, which is longitudinally grooved, as shown at o', in such manner that when the valve G is forced away from its seat on the inner surface of the block F liquid may pass from the part A through the passages alforded by the said groove c', thence to the interior ot' the shell D, and thence out through the opening f. The valve-stem II is provided with an axial rod or extension, ol, around which, between the valve itself and the inner end ot' the part A ot' the bushing, is a spiral spring, I, which tends to force the valve against its seat, and thereby shut olf the exit of the liquid from the part A ot' the bushing to and through lthe passages provided by the groove c ofthe valve-stem H. The innermost end ofthe part A ofthe bushing is provided with one or more openings, through which the liquid may pass direct from the interior of the cask or barrel K into'the part A ofthe bushing. These openings may be eithersmall holes n', as shown in Fig.l, or may comprise a circular opening, as represent- -ed in Fig. 3; or they may be of any other suit- IOO f2 v ermee/2 ableI form or arrangement to permit access of the liquid from the interior of the barrel to the interior ot' the part A'. The outermost end of the actuating valve-stem 71j is provided with a hand-wheel, S, by which it may be turned in one direction to Jforce inward the valve-stem H, to permit the exit of the liquid, or in a reverse direction to permit the closing` of the valve to shut oft' the exit of the liquid.v

It will be observed that inasmuch as the interior of the part A' constitutes a chamber of relatively great magnitude, within which plays the valve G', the latter by its swelling,` or. expansion cannot in anywise materially interfere with the outilow of the liquid to the passages aiiorded by the groove c' in the valvestem. Y, n,

lt is to he understood that when the openings through Whichthe liquid is allowed to pass into the bushing` are so arranged as to render the bearing; or support d.' of the rod or extension d. inadmissible, then in that case a crosspiece may be provided within the part A', having at its center a suitable bearing., m', to receive and sustain the said rod or extension, as represented in Fig. 3.

VV'hat we claim as our invention isl. ln a beer-tap, the bushing` A, having the externally-threaded part a', constituting,` internally a chamber, and having` at its innerend not only inlets for the passage of the liquid, but a guide or bearing, a', theiixed nut a, and internal nut,s, in combination with the threaded block F, the longitudinally-grooved valvestern H, the valve G', and the rod or extensions d, the latter passed through the bearings d', all s'ubstantiallbv as and for the purpose herein set forth.

combined, constructed, and arranged for joint ,Y use and operation, substantially as and for the purpose herein set forth.

3. The bushing A, having the externallythreaded part A', constituting internally a chamber, and having at its inner end not only inlets for the passage ot' the liquid, but a guide' or bearing, d', fixed nut a, and internal thread, s, in combination with the threaded blocl; F, the longitudinally-grooved valve-stem H, having the valve G' and rod or extension d, the latter passed through the bearings'd', the sprin g l', for forcing the valve to its seat, the shell D, having` the nut m, and the threaded Valve-uctnating stem h, passed through the nut m, and

arranged to actuate the valve-stem H to move the valve and the rod or extension d to give stability to the said valve in its movement, all substantially as and for the purpose herein set forth.
